Age of Information in Wireless Networks
Collaborator(s): Prof. Show-Shiow Tzeng
Age of Information (AoI) has become a key metric for evaluating information freshness in real-time status update systems, particularly in sensor networks, the Internet of Things (IoT), and real-time monitoring applications. In multi-node random-access environments, collisions, retransmissions, and successful transmission probabilities in Slotted ALOHA directly affect update packet delivery and, consequently, AoI performance. Therefore, understanding how access probabilities, network size, and packet management strategies influence AoI is essential for designing freshness-oriented communication systems.
